Consider the following about Microbeads.
1.They are plastic Nanoparticles.
2.They are often used in the manufacture of personal care products.
3.They are non-biodegradable.
4.India has banned the use of microbeads.
Select the correct answer using the codes below.
Explanation:
Statement 1 and 2: They are manufactured solid plastic particles of less than one millimeter in their largest dimension.
They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene.
They are used in exfoliating personal care products, toothpastes and in biomedical and health- science research.
Statement 3: Microbeads can cause plastic particle water pollution and pose an environmental hazard for aquatic animals in freshwater and ocean water
Microbeads are washed down the drain, can pass unfiltered through sewage treatment plants and make their way into rivers and canals, resulting in plastic particle water pollution
They're used in soaps because exfoliating products need small, hard particles to rub debris from the skin. These particles can be natural materials, such as ground nut shells or crushed apricot seeds-- or they can be manufactured products like microbeads.
